Abstract
Non-chlorinated, low alkalinity, high retention liquid hard surface cleaner concentrate and use solutions containing an amine oxide surfactant, an anionic surfactant, a hydrophobically modified polymer surfactant, a thinner, and alkali are provided, which form viscous solutions upon dilution and which in cleaning operations, are capable of producing gel-like foams. The composition synergistically exhibits exceptional cleaning performance without the need of chlorine or high levels of caustic.
Claims16
An aqueous concentrate suitable for dilution with water to form a viscous cleaning solution, comprising:
- (a) from about 1 to about 9 weight percent of an amine oxide having the formula:
- ##STR2## wherein R is C.sub.10 to C.sub.18 and wherein each R.sup.1, independently, is selected from the group consisting of methyl, ethyl, and 2-hydroxyethyl;
- (b) from about 1 to about 8 weight percent of an alkyl anionic surfactant selected from the group consisting of the ammonium and alkali metal salts of the alkyl sulfates, olefin sulfonates, alkylether sulfates, alkylaryl sulfonates, alkylarylether sulfates, alkylarylether sulfonates and mixtures thereof, wherein said alkyl groups are minimally C.sub.12 when aryl groups are not present, and wherein said alkylaryl groups are minimally C.sub.16, and wherein said ether groups comprise a polyoxyalkylene group containing from 2 to 4 C.sub.2 to C.sub.4 alkylene oxide residues;
- (c) from about 1 to about 5 weight percent of a polymer having hydrophobic groups selected from the group consisting of acrylates, maleates and sulfonates, said polymer hydrophobically modified by pendant alkyl moieties through carboxylic ester or sulfonate ester linkage;
- (d) a thinner selected from the group consisting of lower alkanols, lower alkanol ethers, and nonionic surfactants prepared by oxyalkylating an alkylphenol or a fatty alcohol with from 4 to 10 C.sub.2 -C.sub.3 alkylene oxide moleties;
- and
- (e) an alkali.
An aqueous concentrate suitable for dilution with water to form a viscous cleaning solution, comprising, by weight:
- (a) from about 1 to 9 percent of an amine oxide having the formula:
- ##STR3## wherein R is C.sub.10 -C.sub.18 alkyl and wherein each R.sup.1, independently, is selected from the group consisting of methyl, ethyl and 2-hydroxyethyl;
- (b) from about 1 to 8 percent of an alkyl anionic surfactant selected from the group consisting of the ammonium and alkali metals salts of the alkyl sulfates, olefin sulfonates, alkylether sulfates, alkylaryl sulfonates, alkylaryether sulfates, alkylaryether sulfonates and mixtures thereof, wherein said alkyl groups are minimally C.sub.12 when aryl groups are not present, and wherein said alkylaryl groups are minimally C.sub.16, and said ether groups comprise a polyoxyalkylene group containing 2 to 4 C.sub.2 to C.sub.4 alkylene oxide residues;
- (c) from about 1 to about 8 percent of a polymer having hydrophilic groups selected from the group consisting of acrylates, maleates and sulfonates, said polymer being hydrophobically modified by pendant alkyl moleties through carboxylic ester or sulfonate ester linkage.
- (d) an effective amount of a thinner selected from the group consisting of lower alkanols, lower alkanol ethers, and nonionic surfactants prepared by oxyalkylating an alkylphenol or a fatty alcohol with from 4 to 10 C.sub.2 -C.sub.3 alkylene oxide moleties;
- and
- (e) an effective amount of an alkali.
